Guided bomb

A guided bomb (also known as a smart bomb, guided bomb unit, or GBU) is a precision-guided munition designed to achieve a smaller Circular error probable.

Because the damage effects of explosive weapons fall off with distance according to a power law, even modest improvements in accuracy (and hence reduction in miss distance) enable a target to be effectively attacked with fewer or smaller bombs. Therefore, with guided weapons, fewer air crews are put at risk, less ordnance spent, and collateral damage reduced.

The creation of precision-guided munitions resulted in the retroactive renaming of older bombs as unguided bombs or "dumb bombs".

Design

Payload

A guided bomb of a given weight must carry fewer explosives to accommodate the guidance mechanisms.

Guidance

Guided bombs carry a guidance system which is usually monitored and controlled from an external device.

Radio

The Germans were first to introduce Precision Guided Munitions (PGMs) in combat, using the 1,400-kg (3,100 lb) MCLOS-guidance Fritz X to successfully attack the Italian battleship Roma in September 1943. The closest Allied equivalents were the 1,000-lb (454 kg) AZON (AZimuth ONly), used in both Europe and the CBI Theater, and the US Navy's Bat, primarily used in the Pacific Theater of World War II which used autonomous, on-board radar guidance. In addition, the U.S. tested the rocket-propelled Gargoyle; it never entered service. No Japanese remotely guided PGMs ever saw service in World War II.

Smart Bomb (video game)

Smart Bomb, also known as Smartbomb and Bombshell, is a timed puzzle videogame for the PSP developed by Core Design Ltd.. It was one of the first video games to be released on the PSP and was at first set to be a big game, yet many control flaws and repetition of levels meant that it was a relatively low selling game.

The aim of the game is to defuse a bomb on the screen while the timer counts down, each level is divided into tiers that get closer to the core of the bomb and once successfully defused the player moves on to the next level.

Gameplay

The player is a member of a fictitious "Counter Terrorist Unit" (unrelated to the Counter Terrorism Unit of the TV show 24), who must defuse bombs found in various locations. Each bomb is rigged with a number of puzzles that all must be completed before the timer on the bomb goes off, and thus ending the game.

The player may select the order of the puzzles within each bomb to attempt. There are several different types of puzzles available in the game, including:
